Intrinsic Phenomena in a Gas-Solid Flow

There are inherent phenomena associated with gas-solid flows. Such phenomena are of considerable interest to a wide spectrum of process applications involving gas-solid flows and can be exemplified by erosion, attrition, pressure-wave propagation, flow instability, and gas-solid turbulence modulation. 

This chapter addresses the various phenomena indicated. In addition, the thermodynamic laws governing physical properties of the gas-solid mixture such as density, pressure, internal energy, and specific heat are introduced. The thermodynamic analysis of gas-solid systems requires revisions or modifications of the thermodynamic laws for a pure gas system. In this chapter, the equation of state of the gas-solid mixture is derived and an isentropic change of state is discussed.
